Octal Bus Transceivers (with 3-state outputs) Description This device has an active low enable input G and a direction control input (DIR). When DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HCT245 transfers true data from one bus to the other. This device does not have schmitt trigger inputs. Features ? LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility ? High Speed Operation: tpd (A to Y) = 12 ns typ (CL = 50 pF) ? High Output Current: Fanout of 15 LSTTL Loads ? Wide Operating Voltage: VCC = 4.5 to 5.5 V ? Low Input Current: 1 μA max ? Low Quiescent Supply Current: ICC (static) = 4 μA max (Ta = 25°C) ? Ordering Information |
